It seems Window's network discovery / name resolution doesn't work anymore on computers freshly reset with the new April update for Windows 10 (Build 1803). (Computers that were merely updated don't seem to be affected.)

My local network consists of a modern NAS drive using samba for sharing, plus a couple other Windows 10 computers (in addition to the one I'm typing on). All computers have the network configured as a private network.

Before the April 1803 update, going to File Explorer -> Network would show a list of windows computers, including the NAS. I could then browse the NAS, mount it as a network drive, etc.

This "network discovery" behavior still works on computers that were merely updated to 1803, however resetting the computer to a fresh 1803 install seems to break network discovery. On reset computers, going to File Explorer --> Network results in Nothing. Nada. No name resolution. No network discovery. Nothing shows up.

When I try to manually connect to \\AS5002T or \ (my NAS) on the updated 1803 computers, it works (I can browse the NAS files). But on the reset 1803 computers, connecting doesn't work anymore at all. In the best case, I just get "Network Path not Found".

Googling "network discovery Windows 1803" shows I'm not the only one having problems. Some people have observed certain "Function Discovery" services not running, and on the reset computer I noticed that SMB 1.0 features are disabled by default.

Anyone know if this is a recognized issue? What fixes there may be? Perhaps people don't know about this issue because it only affects computers reset with 1803?

In total, the problems are for reset, fresh Windows 10 computers with update 1803.

  • Network Discovery is not working, shows no computers on network
  • Cannot connect to Samba share

Everything you need to know is here:


In summary:

SMB 1.0 is BAD. Don't use it. You probably don't need it anyway (we'll get to that).

Because it's so bad, Microsoft has begun removing it from Windows completely, starting with the Windows 10 1709 Fall Creators Update. Right now, if you just update an existing system that already had it, you get to keep it. But if you start fresh with a new copy of Windows, it won't be there. Soon, it won't even be available to install, and soon after that it will be actively removed by a normal Windows Update. At that point, it will likely just be a normal monthly patch, and not even a full feature upgrade.

In other words, there's no point bothering to re-install this back on your system. You're setting yourself up for a fight that's not gonna go your way. You might win today's battle, but the problem's gonna come back (probably sooner than you think) and you'll eventually lose that war.

Fortunately, very few things still require SMB 1.0, and most of those that do are the result of running outdated software on some other system, such that you can also update the other system and restore service.

One of the most noticeable places which still relies on SMB 1.0 by default is the network browsing feature in Windows Explorer (formerly Network Neighborhood). However, you can fix this, too, without using SMB 1.0:

  • Find the Function Discovery Provider Host and Function Discovery Resource Publication services and set their startup types to Automatic (Delayed Start).
  • The next time you start network browsing, follow the prompts to enable Network discovery.

Do this for all Windows computers on your network, and everything is fine again, using the much nicer WS-DISCOVERY protocol.

  • Any specific protocols that a couple-year-old NAS might support, that might also be Windows friendly in the long term? Also is SMB 1.0 required to be able to see/discover "the network" in the file explorer? The source makes it sound like users won't be able to see network icons any longer. ".........You have old management software that demands admins browse via the so-called ‘network’ aka ‘network neighborhood’ master browser list......" Oh, I see this is what you talk about in the last half.

  • Make sure the NAS is running recent firmware. Beyond that, it probably didn't need SMB1 in order for the drive mapping to work. May 15, 2018 at 1:52
  • I have an old and working Windows server 2003 which shares I can't access now from Win10 1803 build. Could I install samba instead of SMB1?

  • Microsoft support ( support.microsoft.com/en-us/help/4034314/… ) includes your "fix" but says this about it: "Note We recommend that you map drives and printers instead of enabling this feature, which still requires searching and browsing for their devices. Mapped resources are easier to locate, require less training, and are safer to use." Jan 7, 2019 at 15:04

Recommended Actions

It seems that windows is abandoning SMB 1.0, and currently my NAS (which is only two years old) doesn't support whatever "Network Explorer" protocol they have moved on to. So for now, your supposed to leave SMB 1.0 disabled, manually enter the necessary information into Credential Manager, and manually connect to the network drive. Setting the two "Function Discovery" services to Auto Delayed didn't help me, but that is supposed to recover the Network Explorer.

To recover the behavior where you are prompted for username and password when connecting to certain NAS devices, I had to "enable insecure guest logons". Otherwise Windows will just give up after trying your username (not telling you what failed nor why).

Alternative Actions (to recover the "old behavior" of windows)

Enabling the optional feature SMB 1.0/CIFS Client and restarting the computer will fix network discovery.

You may still get "Error code 0x80070035 - The network path was not found" if the samba device you are connecting to does not have a user account name that matches your windows account name.

The freshly-reset Windows 10 1803 computer with SMB 1.0 Client feature enabled cannot connect to a samba server. Error code 0x80070035 "The network path was not found.

There are several ways to fix the above "missing username" issue (despite it appearing that its a different kind of issue). The first is by placing a valid entry in the Windows Credential Manager. In my case, the entry was for the domain AS5002T, the username admin, and my password.

enter image description here

A second method, which will recover the way windows worked in the past, is to instead "enable insecure guest logons". Insecure guest logons are used on many consumer NAS devices, as a way to let unauthenticated network users "preview" the shares on the NAS.

A third method would be to simply add your windows username to the samba server's list of usernames.

  • My solution for not being prompted for username and password was to delete the Credential Manager entry. The device then asked me for a username and password every time I connected.

  • That's strange because that issue occurs for me when Credential Manager is empty. If empty, when I try to connect via File Explorer I get "network path not found", and if I connect via command line, I get "insecure guest logon is disabled" or whatever.

    Thanks for this, the function discovery services thing didn't help me and we've a variety of operating systems on our LAN which one morning were simply hidden from just one PC on the network. It is horrendous that MS would push an update that has this effect without providing some advisory prior to installation.

i think i have been having the same issue ubuntu server/windows 10

my solution was to install a WSDD daemon, the one linked below requires no configuration other than changing your service file



If you have stumbled upon this question, there is a solution for Windows-Windows Samba connection: if you changed the UAC settings in secpol.msc (Security Policies), so you could be admin for whole computer - you may need to do that on both machines if you want them to see each other. Few hours spent to find this.
